Figure 34.11 Which of the following statements about the digestive system is false? Chyme is a mixture of food and digestive juices that is produced in the stomach. Food enters the large intestine before the small intestine. In the small intestine, chyme mixes with bile, which emulsifies fats. The stomach is separated from the small intestine by the pylloric sphincter.

Figure 34.12 Which of the following statements about the small intestine is false? Absorptive cells that line the small intestine have microvilli, small projections that increase surface area and aid in the absorption of food. The inside of the small intestine has many folds, called villi. Microvilli are lined with blood vessels as well as lymphatic vessels. The inside of the small intestine is called the lumen.
The digestive juices from the liver are delivered to the. stomach liver duodenum colon
8. The middle portion of the small intestine is the A. JejunumB. DuodenumC. IleumD. Cecum 9. Parietal cells secreteA. SecretinB. Hydrochloric acidC. GastrinD. Pepsinogen 10. The upper esophageal sphincter consists of A. Smooth muscleB. Lymphoid tissueC. Skeletal muscleD. A combination of smooth and skeletal muscle
10. Pancreatic digestive secretions include: a. to buffer acidic gastric juices. b. to dilute acidic gastric juices. c. to continue chemical digestion in the small intestine.
IX. Sequerice of Events: Fat Digestion Arrange the events by inserting numbers in the spaces provided. The first step has been provided to get you started. A. A fat globule enters the duodenum. B. Pancreatic lipase begins to digest fat. C. Triglycerides travel through the lymphatic system and enter the bloodstream at the ieft subclavian vein. D. Glycerol and short-chain fatty acids are absorbed into the bloodstream of villi, and long-chain fatty acids are absorbed into the walls of the villi. E. Two substances in bile (lecithin and bile salts) emulsify fat. F. Fats are broken down into a mixture of glycerol, short-chairn fatty acids, long-chain fatty acids, and monoglycerides. G. The gallbladder secretes bile. H. Triglycerides enter the lacteal of the villi.
9.How does gastrointestinal tract evade dehydration? Read and analyze the question and choices CAREFULLY; more importantly, ALWAYS CHOOSE the BEST answer. Water is an important digestive enzyme in the stomach. Alternating wave-like contraction and relaxatio of the oral (mouth) muscles reabsorbs water which will be transported to the urinary system The water we drink will be mostly absord by the blood vessels attached to the esophagus and stomach. Normal peristaltic movements in the large intestine ensure reabsorption of water that will be delivered to the circulatory system.
